How does J Collis Browne's mixture work?

Morphine is a type of medicine called an opioid. In high doses it is a strong painkiller, but it also has cough suppressant and anti-diarrhoeal actions. This medicine contains a low dose of morphine that is not a painkiller and is used purely for its anti-diarrhoeal or cough suppressant effect.

MOST POPULAR

Morphine relieves a cough by reducing the nerve signals sent from a part of the brain called the coughing centre to the muscles that produce coughing. This blocks the cough reflex and is useful for stopping a tickly, irritating unproductive cough.

Morphine relieves diarrhoea by reducing the speed at which the gut contents are pushed through the intestines, allowing more time for water and electrolytes to be reabsorbed back into the body. This results in firmer stools that are passed less frequently.

Peppermint oil acts directly on the smooth muscle in the bowel wall, causing it to relax. This helps reduce painful spasms and pressure in the bowel and eases bloating and wind associated with the diarrhoea.

What should I know before taking J Collis Browne's mixture?

If you have any of the following symptoms with your cough you should not take this medicine and consult your doctor so that the cough can be investigated further:

coughing up phlegm that is green, rusty brown, yellow, blood-stained or foul smelling

shortness of breath, wheezing or difficulty breathing

chest pain

pain and swelling in your calf

sudden weight loss

recurrent night-time cough or a long-term persistent cough.

If any of the following apply to your diarrhoea you should not take this medicine and consult a doctor instead:

if your diarrhoea started either during or after taking a course of antibiotics

if the diarrhoea contains yellow or greenish mucus or blood

if you also have a fever.

Acute diarrhoea makes you lose more fluids and salt than you usually would and can make you dehydrated. This medicine only treats the diarrhoea symptoms and so will not rehydrate you. You should ensure that you drink plenty of fluids, and you may also want to take an oral rehydration therapy, which is a soluble powder containing sugars and salts, to help rehydrate you. This is particularly important for frail and elderly people and children. Rehydration salts can be bought from pharmacies.

It may be an offence to drive while you are taking J Collis Browne's mixture. Do not drive if you think it affects your ability to drive safely, for example if it makes you feel sleepy, dizzy, unable to concentrate or make decisions, or if you have blurred or double vision.

Don't drink alcohol while taking J Collis Browne's mixture, as this will make you more likely to get side effects like drowsiness, dizziness, confusion and blurred vision.

As this medicine contains morphine, travellers wanting to take it abroad might be advised to carry a doctor's letter with them explaining why the medicine is necessary.
